But at some point, there was no other option than creating something that provided all these features, taking the best ideas from previous tools, and combining them in the best way possible, using language features that weren't even available before (Python 3.6+ type hints).

## Previous tools

    Set<Feature<?>> features = computeMultimapAsMapGetFeatures(parentBuilder.getFeatures());
    if (Collections.disjoint(features, EnumSet.allOf(CollectionSize.class))) {
      return new TestSuite();
    } else {
      return SetTestSuiteBuilder.using(
              new MultimapAsMapGetGenerator<K, V>(parentBuilder.getSubjectGenerator()))
          .withFeatures(features)

Agora vamos dizer que você queira adicionar uma tradução para a seção  [Recursos](features.md){.internal-link target=_blank}.

* Copie o arquivo em:

```
docs/en/docs/features.md
```

* Cole ele exatamente no mesmo local mas para a linguagem que você quer traduzir, por exemplo:

```
